My understanding of the $16/hr is 40-45% of the car has to be produced at that wage or higher. This includes the USA produced percentage. IMHO it does not mean Mexico jobs at $16 but a percentage of the car. This is the wordsmithing from The USA Office of Trade, "This deal uses trade rules to drive higher wages by requiring that 40-45 percent of auto content be made by workers earning at least $16 per hour." Notice the statement only says "workers" not Mexican Workers. I have also attached the doc from USA office.
